In a different scenario, it could be part of a training exercise gone wrong. The Avengers were trying to teach Spiderman a new combat move that involved some light tickling to test his reflexes. But it turns into a full - on tickle fest, with Peter Parker (Spiderman) trying to escape the clutches of his teammates while everyone is having a great time.
Maybe Spiderman has been a bit too serious lately, so the Avengers decide to cheer him up with some tickling. Natasha Romanoff uses her spy skills to find his most ticklish spots. They tickle him until he's laughing uncontrollably, and this helps him relax and forget about his recent troubles.
Another plotline could be Spiderman's relationships with other characters during the Civil War. He might form a closer bond with Captain America as he begins to understand Cap's perspective on the Sokovia Accords. Or perhaps he has a falling out with a fellow Avenger who doesn't agree with his stance. This could lead to some intense emotional moments and character development for Spiderman.
Perhaps there is a powerful artifact that both Spiderman and the Avengers are after. They end up in a conflict over it. Spiderman, with his street - smart ways, tries to outwit the Avengers and get the artifact for himself, believing he can use it for good in his own way.
Well, perhaps Spiderman is poisoned by a new type of toxin from a villain. The Avengers then scramble to find an antidote. Black Widow uses her espionage skills to track down the origin of the toxin, while Hulk, in his Banner form, tries to analyze it scientifically. Thor might also use his Asgardian knowledge to see if there are any magical cures. In the meantime, they keep Spiderman comfortable and safe from further attacks.
There could also be a plotline where they both enter a mysterious tournament. They have to fight other superheroes and villains in a series of battles. Along the way, they learn more about each other's capabilities and form a stronger bond.
Perhaps there's a power - stealing device in the fanfiction. It's stolen by a villain and used on the Avengers, but Gwen is immune. So the Avengers, now with reduced powers, end up fighting Gwen who is trying to get the device back. Or it could be that Gwen discovers a threat to her world that the Avengers don't believe in, and they try to stop her from taking action, leading to a conflict.
In a more complex plot, it could be set in an alternate universe where Severus and Harry are on the same side from the start. As part of a team - building exercise of sorts, Severus uses tickling as a way to break the ice with Harry and the other young wizards. This leads to a series of adventures where their new - found camaraderie is tested and strengthened through various challenges, with the tickling incident being a recurring theme that is both humorous and a bonding factor.
Well, in such a fanfic, the Avengers could initially be skeptical of Spiderman. Maybe they think he's too young and inexperienced. But then Spiderman could prove himself by using his unique web - slinging skills to save one of the Avengers from a tricky situation. And they start to see his potential and welcome him to the team.
Well, perhaps in this fanfic, the Avengers misunderstand Spiderman's actions. Maybe they think he's been compromised by some powerful enemy force, so they decide to kidnap him to figure out what's really going on. They could take him to a secret location, like an abandoned SHIELD base. Then Spiderman has to convince them that he's on their side while also dealing with his own feelings of betrayal.
One possible plotline could be that the Democles Project is a project to create super - soldiers like Captain America, but something goes wrong and the Avengers have to stop the out - of - control super - soldiers. Another could be that the project is about a new energy source, and villains want to steal it, so the Avengers must protect it.
One possible plotline could be her journey to discover her true powers. As the daughter of Poseidon, she might have the ability to control water in unique ways, like creating massive tidal waves or even communicating with sea creatures. She could face challenges from other mythological beings who are jealous of her powers.
